Mycoplasma e Ureaplasma em gestantes HIV- positivas
##plugins.themes.bootstrap3.article.main##
Resumo
Objetivo: Comparar a prevalência cérvico-vaginal das espécies de Mollicutes: Mycoplasma genitalium, M. hominis, Ureaplasma parvum e U. urealyticum entre gestantes de acordo com o status de infecção pelo HIV. Métodos: Trata-se de um estudo longitudinal prospectivo que incluiu 29 gestantes HIV-positivas e 34 HIV-negativas. Todas as participantes responderam um questionário para obtenção de dados sociodemográficos e comportamentais. Amostras cérvico-vaginais foram coletadas e testadas molecularmente para as quatro espécies de Mollicutes. As taxas de prevalência foram comparadas entre os grupos de estudo utilizando o teste exato de Fisher ou qui-quadrado. Resultados: A prevalência de Mollicutes foi superior em mulheres HIV-positivas (51,7%; n=15) quando comparada com o grupo de gestantes HIV-negativas (12,0%; n=4), (p<0,001). A espécie mais frequentemente detectada foi U. parvum, presente em 12 (41,4%) amostras de gestantes HIV-positivas e 2 (6,0%) amostras de gestantes HIV-negativas (p<0,01). A análise longitudinal mostrou que gestantes com HIV tiveram um número maior de momentos positivos para Mollicutes quando comparadas às mulheres HIV-negativas (p = 0,01). Conclusão: Os dados de prevalência de Mollicutes aqui apresentados pode nortear estratégias diagnósticas para tais microrganismos, se clinicamente indicado.
